Learning Outcomes
• Be able to recognise the unwell child
• To apply a systematic approach to assessing an unwell child utilising a primary survey
• To discuss the primary survey management of care for the unwell child

AirwayAssess vocalisations - crying or talking indicate ventilation and some degree of airway patency
Look for chest/ abdominal movement, symmetry and recessionListen for breathing sounds and stridorFeel for expired air
Reassess after using any airway opening manoeuvre

Management of AirwayThere are four steps in the management of the airway:1. OPEN the airway – Posture, chin lift/jaw thrust2. CLEAR the airway – Suction, finger sweep3. SECURE the airway – Airway adjuncts e.g. oro/nasopharyngeal airway, LMA and ETT4. MONITOR the airway

Effort of BreathingIncreased effort of breathing DOES NOT occur in three circumstances
1. Exhaustion (with imminent resp. arrest)
2. Central respiratory depression
3. Neuromuscular disease
![Page 12: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/12.jpg)
Efficacy of BreathingLook for chest expansion, symmetry and abdominal excursion
Air entry / breath soundsListen in all areas – back, front and mid axillary line
![Page 13: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/13.jpg)
Efficacy of BreathingPulse oximetry is acknowledged as a measure of efficacy
The measurement in air is the most useful, with SpO2 <95% considered abnormal, and <85% potentially life threatening. Normal SpO2 in oxygen does not rule out respiratory failure, with an elevated CO2
A silent chest is a pre-terminal sign
![Page 14: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/14.jpg)
Effect - Adequacy of breathing• Heart rate - Tachycardia/ bradycardia
• SpO2 in room air - SpO2 of <85% is a pre-terminal sign
• Skin colour - Pallor, sweaty, mottling secondary to endogenous epinephrine
• Mental status - Agitation, restlessness, quiet, reduced conscious level, coma
![Page 15: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/15.jpg)
Management of BreathingIs the breathing effective? – Administer O2therapy
If ineffective or apnoea• Airway opening manoeuvres• Support ventilation (adjuncts) or intubation
Reduce stressors• Parents present• Position of comfort

CirculationAs homeostatic mechanisms function particularly well in children, and compensation for inadequate circulatory function is good, a thorough circulation assessment is important
Remember, in a child, it can be difficult to detect circulatory failure until a late stage
![Page 17: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/17.jpg)
CirculationCirculatory assessment should look at both circulatory status and the effects of inadequate circulation on other organs systems.
Heart Rate and BP are classical measures, but skin perfusion such as capillary refill, skin pallor, temperature or turgor can be more useful in detecting the early stages of compensated shock
![Page 18: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/18.jpg)
CirculationHeart Rate
• Tachycardia – key sign of shock• Bradycardia – late sign
Systemic Perfusion• Peripheral pulses - pulse volume weak thready
or absent indicates shock• Skin perfusion - capillary refill, mottled, cool/
warm, turgor
![Page 19: Paediatric Assessment A Structured Approach - Amazon S3 · Airway Assess vocalisations - crying or talking indicate ventilation and some degree of airway patency Look for chest/ abdominal](https://reader033.fdocuments.in/reader033/viewer/2022050715/5d48b71f88c993fc368b6053/html5/thumbnails/19.jpg)
CirculationSystemic Perfusion cont…• Mental status – agitation and altered conscious level
are important signs of circulatory inadequacy and the resultant cerebral hypoperfusion. Infants – irritable, floppy, failure to make eye contact with parents
Blood pressure• A child in shock may have a normal BP. Hypotension
is a late sign – indicates decompensation. • Use a correct sized BP cuff. • End organ perfusion = urinary output (1ml/kg/hr)
